C Program To Find Factorial of a Number using Recursion

technotip.com/...
Lets write a C program to find Factorial of a user input number using Recursion.
Factorial Definition: Factorial of a positive integer n, denoted by n!, is the product of all positive integers less than or equal to n.
Important Note: By convention, Factorial of 0 is 1. i.e., 0! = 1.
Example: 5! = 5 x 4 x 3 x 2 x 1 which is equal to 120. i.e., 5! = 120.
Formula To Calculate Factorial of any positive integer number
We can calculate factorial of any number using this relationship:
num! = num * (num - 1)!
where num is a positive integer number.

Void main bhi le sakte the kya?

[@technotipDOTorg]

Yes you can. But it's always good practice to have int main() and then return 0 at the end. Returning 0 indicates(to the operating system) that the code inside main executed with out any error.

thank you sir my problem solve

[@down2uranus]

This was really helpful, I did spent a lot of time trying to understand the logic before watching this video, thanks techotip

[@harshanaththanayaka1637]

thank you

[@ariefsaferman]

Cool.

[@deepahaasan6131]

Waste didn't get the output
I just copy the same coding and tried in my laptop i didn't get the right output

[@deepahaasan6131]

In output if i enter any number
For eg : i entered 7
So output coming as return 0 is 1
